I need a box ASAP!! HELP

Hello, I just bought a Rockford Fosgate 12" Punch HX2 subwoofer and I should have it by Tuesday. I need a 2.5 cu ft box after displacement tuned @ 33 HZ. The only limitation I have is that the box can not be over 13" high. Please can someone make me a box for a reasonable price The box DOES NOT need to be carpeted!!
Please someone help me out and pics of your work would be appreciated.
